Abstract

Sposób rafinacji żeliwa wysokojakościowego sferoidalnego, w którym żeliwo poddaje się sferoidyzacji i modyfikacji poprzez wprowadzenie do roztopionego metalu kompozycji znanych sferoidyzatorów i modyfikatorów oraz rafinacji gazem obojętnym charakteryzuje się tym, że żeliwo poddaje się dwuetapowej rafinacji, przy czym pierwotną rafinację przeprowadza się w piecu, a następnie po przelaniu ciekłego żeliwa do kadzi i w trakcie lub po przeprowadzeniu zabiegu sferoidyzacji ciekłe żeliwo poddaje się zabiegowi wtórnej rafinacji.The method of refining high-quality ductile iron, in which the cast iron is spheroidized and modified by introducing a composition of known spheroidizers and modifiers into the molten metal, and refining with inert gas, is characterized in that the cast iron is subjected to a two-stage refining, with the primary refining being carried out in a furnace and then after pouring the liquid cast iron into the ladle and during or after the spheroidization treatment, the liquid cast iron is subjected to a secondary refining treatment.
